ok say i got a site with 3 pages of content. but only 1 physical page. ie



------------------
link1 - points to "generatepage.php?id=1"
link2 - points to "generatepage.php?id=2"
link3 points to "generatepage.php?id=3"
------------------


generatepage.php

generates a full page (page title, images, all the text etc) depending on the link clicked.

Does your site get seen as having 3 page or 1? in the search engine eyes?

I'm not definate, but if you put meta tags and keywords etc in your generatepage.php, the generated pages "MIGHT" be cached by the search engine spiders or they might not. But I think on the whole it is seen one page.

It could be like when you search for a product sometimes you get a generated page on goolge or something.

Not sure. But that my 2 cents.

search engines will usually do fine with urls like that. however, in the past google has seemed at times to ignore the parameter "id". i'd change it to ?page= or something just to be safe.
